Zener Barriers

A Zener Barrier is a
device that limits the voltage and current entering a hazardous area for use by
intrinsically safe equipment. The voltage
is limited or clamped by a Zener diode and the output current is limited by an
output resistor, a fuse is also used in the circuit to protect the Zener diode.
As per any intrinsically safety equipment, the Zener barrier allows cables to
short circuit to each other or to metallic parts connected to ground without causing
dangerous situations.
